The depth of the ocean is deeper than the first peak of the land, Mount Everest, and the deepest place is the Mariana Trench, which is more than 11,000 meters deep.

In the ocean of 100 meters, it is already difficult to feel the light with the naked eye, so in the depths of the ocean, it is even more dark.
Therefore, fish living in the deep sea are generally ugly, and of course, there are some creatures with slightly decent appearance, such as sunfish.
Let's take a look at the sunfish and see why they can spawn 300 million eggs at a time, but they are vulnerable creatures. Some say it's because it's eaten by seals and doesn't run.
Ugly sunfish
The fertility rate of the sunfish is extremely high
To say that among the fish, the most abundant is the sunfish, its scientific name is the sunfish, is the sunfish family, the genus of the sunfish.
We usually see the introduction of fish, in the breeding season, a fish lays thousands of eggs.
But in the case of the sunfish, one can even lay 300 million eggs.
However, this does not have much effect, because the sunfish do not care about the death of the cubs after laying their eggs.
So the little sunfish, almost abandoned at birth, to know that in the deep sea, there are dangers everywhere.
Sunfish pups
Although the sunfish is the largest bony fish in the deep sea, the small sunfish is only 2 mm large and weighs 1 gram.
Those deep-sea fish are not easy to mess with, they have a big mouth, the small sunfish will die, sometimes the number is small, not even enough to plug the teeth.
According to expert statistics, the survival rate of small bluefish is only one in ten million, that is to say, of the 300 million fish eggs, only 30 sunfish can survive the growth period and successfully grow.
Of course, this Buddhist breeding method is also the result of the high fertility rate of sunfish.
Super small sunfish
The sunfish are vulnerable creatures
The scarcity of surviving numbers is also one of the reasons why sunfish become vulnerable creatures, but in this process, of course, human participation is indispensable.
In fact, for a long time, the sunfish was not welcomed by fishermen, and it would be released almost after being caught, because the taste was not delicious.
Caused by human activities
One is because the adult sunfish is very large, can grow to 3-4 meters tall, and weighs 3000 kg, which can be described as crazy development compared to small sunfish.
Nowadays, there are very few people who eat sunfish, the most typical of which is the Japanese sunfish intestine.
Caught sunfish
Later, it was found that liver oil extracted from the liver of sunfish can be used to treat burns, falls and bruises.
Therefore, the adult sunfish, which was already rare in number, was caught in large quantities, and the number dropped even more.
Of course, their numbers were also greatly threatened before the value of the sunfish was discovered.
This time, it is because of human bycatch, because the sunfish, as a distant-water fish, often overlaps with the human fishing area, so it is inevitable that some sunfish will come ashore in a net.
Caught sunfish
It is understood that about 340,000 sunfish are caught ashore in South Africa every year, and the number of sunfish caught in the swordfish fisheries in California accounts for 29% of the total catch each year, which is more than the number of target fishing targets for fishermen.
In addition to human fishing, some sunfish have also lost their lives due to human activities.
Marine pollution has always been a problem of great importance to us, because the garbage that flows into the ocean has caused a large number of fish deaths.
One of the most likely to be mistakenly eaten by sunfish is plastic bags, because the main food source of sunfish is jellyfish.
Jellyfish-like marine litter
In the deep sea, due to low visibility, it is difficult for them to distinguish between plastic and jellyfish, so there are a large number of sunfish because of eating plastic bags, resulting in stuck in the throat, suffocation and death.
When these plastic bags enter the stomach of the sunfish, they will accumulate in large quantities because they cannot digest, and over time, they may be unable to eat because their stomachs are filled, and they will be starved to death.
Quietly nibbled by seals
In addition to human activities, the sunfish are also difficult to escape the nibbling of predators.
Mola that is nibbled on
However, in the ocean, I am afraid that most creatures will choose small sunfish, although it has many bumps on its body, but the taste will be better than that of adult sunfish.
But there is one creature that does not dislike the sunfish, and that is the seal.
A photographer once photographed a seal nibbling on a sunfish, and strangely enough, the sunfish not only did not resist, but even had no idea of escaping, but just leisurely let the seals nibble.
This picture simply shocked people for a hundred years, knowing the Sunfish Buddhist system, but they did not expect to have reached such a point.
Quietly eaten
So despite the huge spawning sheer, sunfish can't help but be made, and if they're not too hard to eat, they might be more than vulnerable.
Why doesn't the sunfish run away?
If the sunfish can have a certain ability to fight back, or even escape, perhaps their fate is not so tragic.
In fact, you can't blame the sunfish for not running, mainly because it can't run.
What we usually see is the side of the sunfish, this side is indeed like a vehicle overturning, and from the front, it is completely a big head doll.
Big-headed doll-like sunfish
It is understood that the head of the sunfish even occupies 90% of its body, and we can hardly see their tails from the side, so the short presence can not help the sunfish swim fast.
Most marine life, as well as fish, rely on the tail fin to provide power, but the sunfish has neglected this important part in the process of evolution, resulting in serious degradation.
Today's sunfish only have a "false tail" at the end of the dorsal fin and pectoral fin, and they can only provide help to maintain balance, so the driving force provided to the sunfish is very small.
The "false tail" of the sunfish
Therefore, the speed of the sunfish in the ocean is only 3.2 km / h, which is simply slower than the speed of human walking.
In addition, although the "false tail" does not play a big role, it can at least provide a little power for the swimming of the sunfish.
However, in the ocean, there are always some naughty creatures that will deliberately tear off the pectoral and dorsal fins of the juvenile sunfish, causing them to slowly sink to the bottom of the sea and die.
Because sunfish are the only thermostatic fish found today, they simply cannot fully adapt to the low temperatures of the depths of the ocean.

In such a body structure, when facing the attack of predators, the sunfish already knows that they have no chance to fight back or escape, so they simply let them eat happily.
Magical sunfish
The sunfish is a typical creature whose father does not hurt and whose mother does not love, whether it is when they are young or after they grow up, their fate is very miserable, but this does not affect their Buddhist life.
In the ocean, they will only devour small creatures, because the mouth is like a cherry mouth in front of its huge size.
Cherry-like mouth
Not only is it difficult to have bite force, not even a tooth in a mouth, the only tooth is still in the throat, but they can still grow to such a large size.
Perhaps the sunfish is also in order to prevent itself from being eaten, so it will secrete a substance on the surface of the body, which can effectively treat the injuries of the fish, so it is often seen that the sunfish are surrounded by a group of fish.
It has also become a marine doctor, and some of the surrounding fish will also glow, and from the side, the sunfish looks like a moon in the sea, so it is also called "moon fish".
A cluster of sunfish
In addition, the sunfish also like to go to the sea to bask in the sun, for this expert analysis, part of the reason is to maintain their body temperature, as a constant temperature fish, in the deep sea to hunt can not freeze themselves to death.
Another part of the reason may be to remove the parasites from their own body, due to slow action, so many parasites have found them, these parasites have more than 50 types, and even scientists have found parasites on these parasites.
So when the sunfish float on the surface of the water to bask in the sun, you can also ask the birds to help clean up the bugs.
Sunbathing sunfish
In this way, the marine life of the sunfish is actually quite interesting, although their own encounters are not good, but they can still ignore it and let themselves survive better in the Buddhist life.
